Abstract: A method for Kraft pulping employing a modified cooking process in conjunction with polysulfide pulping tech-nologies to obtain higher pulping yields than obtained in the prior art.  The total required alkali charge (polysulfide liquor) is added to the beginning of a cook, and after all polysulfide has essentially reacted with lignocellulosic material at temperature below that at which no significant carbohydrate degradation occurs, a first quantity of the cooking liquor high in effective alkali (EA) concentra-tion is removed from a first point in the pulping process and replaced with a cooking liquor low in EA concentration removed from another process point. The first quantity is then added elsewhere in the pulping process, where the EA concentration is low. This cooking liquor "exchange" obtains the full yield benefit from polysulfide pulping and a more uniform EA concentration profile to retain the major benefits of modified cooking.

Abstract: A communication system incorporates a multiplexing scheme so that a base node that schedules user equipment (UE) can determine whether an ACK/NACK and/or a service request (SR) has been re-ceived when both uplink (UL) transmissions are simulta-neously scheduled. Significant complexity reduction, bet-ter link efficiency, and higher multiplexing capability since the base node can interpret selective use by the UE of ei-ther the ACK/NACK or SR UL channel. Such interpreta-tion can be extended to when multiple downlink (DL) transmission modes can be used, specifically DL single in-put multiple output (SIMO), DL multiple input multiple output (MIMO) with rank 1 transmission, and DL MIMO  with rank 2 transmission. Based upon knowledge of the scheduling and DL transmission mode, the base node does not have to blind decode a number of possibilities due to the mapping of possible responses from the UE. In addi-tion, the multiplexing scheme is applicable to FDD and TDD.

Abstract: The invention relates to a method for purifying biogas for extracting methane, where components present in biogas, such as carbon dioxide, sulfur compounds, and ammoniac are separated in a plurality of different process steps, and a system suitable for performing the method.  The aim of providing a method for purifying biogas for extracting methane, characterized by low energy consumption and allowing an increase in methane content of at least 10%, is achieved by the following characteristics: In a first purifying step, carbon dioxide, hydrogen sulfide, ammoniac, and other water-soluble organic substances present in the raw gas are removed in a washing column K1 at standard pressure or at overpressure of up to 6 bar by means of fresh water, wherein methane gas having a methane content of at least 65% is drawn off at the head of the washing column K1. Methane and carbon dioxide dissolved in the wash water are sequentially separated from the contaminated wash water discharged from the washing stage K1, in a first stripping column K2 and subsequently in a second stripping column K3, by adding stripping air under standard pressure.    An oxygenic stripping gas having fuel gas quality arises in the first stripping stage K1. The purified wash water accruing in the second stripping stage is returned to the washing stage K1.
